But, I also need to store the last modified date of the file in the database as well. How would I accomplish this?

View 1 RepliesIs it possible to download a file and set its Date Modified attribute by means of Ajax? I tried to use server-side code below but couldn't set Date Modified although I explicitly used "Last-Modified" Response header:
try{
Response.Clear();
Response.AppendHeader("Content-Disposition", "attachment; filename="+l_attchmntFileSpec);
Response.ContentType = "application/octet-stream";
Response.AppendHeader("Last-Modified", "Tue, 15 Nov 2010 12:45:26 GMT");
Response.BinaryWrite(l_attchmntToDownload);
Response.End();
}
catch (Exception Ex)
{ ...
}
Note: The file in question is stored in my database. It is represented by byte array l_attchmntToDownload.
I have a page which lists all the files in a particular folder (all PDFs), using a data-table and gridview.
I'm currently sorting this table by the filename (by using a dataview), which isn't that helpful, and I want the gridview of files sorted by the file created or file modified date (as recorded in Windows).
If that's not possible, a second option would be to extract the date from the file name string (no problem doing that), and sort the dataview/datatable or gridview based on that. Example Filename: DailySalesReport-1-15-2010. My only hangup with this is how do I sort on date, when it's a string value? Convert to date? How would I sort the whole dataset based on this converted value?

I have an ASP.Net ListBox that I'm trying to populate via jQuery, using the following snippet:
$("#MyList_btnAddAll").click(function(e) {
e.preventDefault();
$('#MyList_lstAll option').appendTo('#MyList_lstSelected');
});
The code has two ListBoxes in fact, one a "source" and the other a "destination". As you can tell above the ListBoxes are MyList_lstAll and MyList_lstSelected. These are rendered in the browser as <select> elements, as you'd expect.
The jQuery is working great, the items are moving from one ListBox to the other, the DOM is updated but when I submit this form (not using jQuery), the ListBoxes don't reflect this change on postback.
I realize my modifications via jQuery aren't available in ViewState but I thought since the DOM was updated these changes would be part of the postback data? But in the codebehind after postback the ListBox contents haven't changed. Does anyone know what might be going on and what I can do about it?
I am developing a website, in which client uploads some document files like doc, docx, htm, html, txt, pdf etc. I want to retrieve last modified date of an uploaded file. I have created one handler(.ashx) which does the job of saving the files.
Following is the code:
HttpPostedFile file = context.Request.Files[i];
string fileName = file.FileName;
file.SaveAs(Path.Combine(uploadPath, filename));
As you can see, its very simple to save the file using file.SaveAs() method. But this HttpPostedFile class is not exposing any property to retrieve last modified date of file.
how to retrieve last modified date of file before saving it to hard disk?
i used below code for date time picker validation but it's not working.
Actually I want a date time picker which date dd/mm/yyyy format date. With validation for start and end date. Also for manual entry it should take only no. and for date rest like / or, will be auto formatted.means user should not be able to enter it.

I am getting the following error
The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).
on adding the following code
HtmlGenericControl ctrl = new HtmlGenericControl("NOSCRIPT");
ctrl.InnerHtml = string.Format("<meta http-equiv=REFRESH content=0;URL={0}>", targeturl);
Page.Header.Controls.Add(ctrl);
May be the below script has some problem
<script type="text/javascript" >
function myfunc()
{
var pas,simve,saue,tsh;
pas=document.getElementById('<%=TextBox2.ClientID%>').value;
simve=hex_md5(pas);
saue='<%=Session["saltval"]%>';
var stsh=simve+saue;
tsh=hex_md5(stsh);
document.getElementById('<%=TextBox2.ClientID%>').value=tsh;
}

I have an ASHX handler or an ASPX page (the problem happens in both cases).
The web client sends a request containing If-None-Match and/or If-Modified-Since headers but context.Request.Headers.Get("If-None-Match") or context.Request.Headers.Get("If-Modified-Since") is null in the handler.
The same script works in my local development machine but it doesn't work in the online machine (both are running IIS7 on Win 2008, .NET 3.5)
I have this code that does not return a 304 not modified, instead always a 200 ok found. Any clues what I'm doing wrong?

I'm trying to access the innerHTML of a span tag modified by jQuery using C#. This is my first project shunning the AJAX libs in favor of jQuery, so I'm not sure how I can get the codebehind to recognize the manipulated innerHTML. I've set all the spans I want to tap into with runat="server", but all I pull are the values I've set when the page was designed.
What steps should I be taking to enable communication between the client-side and my codebehind, and am I even using the best practice here?
I keep a label on the master page of my site that indicates when the site was last updated. I wanted to know if there was a quick and easy way to have the system update the date in the label everytime i compile the solution so the last updated field is always correct even if i happen to forget to update it manually.
View 3 RepliesI am using an instance of DirectoryInfo to browse and retrive the files and some file attributes on a physical directory. This is displayed in a html table. But if you have for example text files (.txt) or word dokuments (.docx) How can I display the correct icon that is associated with the file in my html table? And further on how can I reach the user who modified the file the last time? Where is that info saved?
Is the DirectoryInfo the object I should use for this purpose? or are there other objects or functions that I should looking at?

I'm developing a blog application shared by non-profit organizations. I want each organization to be able to change their own blog settings. I have taken a singleton pattern (from BlogEngine.net) and modified it. (I understand that it is no longer a singleton pattern.) I have tested this approach and it seems to work fine in a development environment. Is this pattern a good practice? Are there issues, which may arise when this is placed in a production environment?
public class UserBlogSettings
{
private UserBlogSettings()
{
Load();
}
public static UserBlogSettings Instance
{
get
{
string cacheKey = "UserBlogSettings-" + HttpContext.Current.Session["userOrgName"].ToString();
object cacheItem = HttpRuntime.Cache[cacheKey] as UserBlogSettings;
if (cacheItem == null)
{
cacheItem = new UserBlogSettings();
HttpRuntime.Cache.Insert(cacheKey, cacheItem, null, DateTime.Now.AddMinutes(1),
Cache.NoSlidingExpiration);
}
return (UserBlogSettings) cacheItem;
}
}
}

I recently purchased the source code of an existing DotNetNuke module in order to make a few modifications. The source of the module contains various .ascx, ascx.resx and .ascx.vb files. as well as a main.dll file. Lets call them:
myfile.ascx
myfile.ascx.resx
myfile.ascx.vb
myfile.dll
I'm using Visual Studio 2008 PRO.
I've made a few changes to "myfile.ascx.vb". When I rebuild "my_module" via Build --> Rebuild my_module, I get confirmation that there are no errors in the Error List. I then upload a fresh copy of "mydll.dll" from the "/obj/release/" folder on my local machine up to the "/bin/" folder on my DotNetNuke site.
The issue that I'm having is that the changes that I made to "myfile.ascx.vb" are not appearing on my DotNetNuke site. Are there additional files that need to uploaded? I've checked timestamps on all of my local files and the only files that are updated after the build is "mydll.dll".
We are using membership and roles.. is there anyway to setup a user that cannot be deleted?
